Changing Jockeys
You would think that most trainers would choose to use the same jockeys for the
same horse week after week. But this is not the case. 70% of all horses running
had a different jockey riding last time compared to today.
Sometimes trainers change jockeys because they want to use the services of
an apprentice, or not, or because they may want a top class jockey to ride
today whilst in previous races a bread and butter jockey has done the steering.
It should therefore be possible to identify trainers who are good at certain
jockey changes.
Before we look at the list, lets first check the stats for when a trainer
puts up a poor, Ok, or good jockey.

Ok=Course Win% 7% < 15%
Good=Course Win% 15%+
e.g. Darryll Holland has a Course Win% (strike rate) of 18% at Nottingham and
would therefore be a 'Good' jockey |
It is clear, that no matter which jockey was aboard last time, it is always
best to ensure a poor jockey is not riding today! Good jockeys (those with a
course win% of 15% or more) consistently win about 15% of the time, whereas
poor jockeys win only 6% of the time.
It would have been interesting to see if there were any big differences from
when using a poor jockey or a good jockey LTO but as the table shows, there is
nothing of significance.

Only 'claiming'
apprentices (3lb, 5lb, 7lb) are included in the table. Races for Amateurs,
Ladies and Apprentices only are excluded. |
Again, there is not much information gleaned from this table. The reason is
because the the data is too generic. Overall you could say that when a trainer
uses a claiming apprentice for a horse, where in it's last race a professional
jockey was onboard, that horse wins about 9% of the time and makes a loss of
34%.
The following table shows the best and worst trainers for changing jockeys

At the top of the table is Bryan Smart. He has had 7 winners from 79
attempts when putting an apprentice on a horse where previously the horse was
ridden by a professional. The profit returned was 86%. Stuart Williams seems to
be the king with this technique. He has achieved a better strike rate from a
greater number of attempts.
Right at the bottom of the table is Hugh Collingridge with 0 wins from 56
attempts.
We have included Alan Berry in this list to allow comparision with the
apprentice to pro jockey table below. Note that Berry has a very poor record
with claiming apprentices regardless of who rode the horse last time.

At the top of this table is Willie Haggas. He has had 10 winners from 51
attempts when using a professional jockey after an apprentice had previous
ridden the horse.
Right at the bottom of the table is D A Nolan with 0 wins from 70 attempts.
Note too that this end of the table shows 'gambling' trainers such as Norma
Macauley and Conrad Allen.
Although Alan Berry is neither really good or bad with this technique, he is
shown in table to indicate the difference in success he achieves when going the
other way. In the previous table he made a loss of 84% but this way round the
loss is just 19%.
